LANCING DEVICES AND METHODS
First Claim
1. A lancing device comprising:
- a housing having spaced apart proximal and distal ends disposed along a longitudinal axis;
a movable member disposed in the housing and configured for movement along the longitudinal axis;
a collar partially disposed in the housing and coupled to the movable member so that the collar is movable as a unit with the movable member;
a lancet coupled to the collar;
a rotatable ring coupled to the collar; and
a lancet depth adjustment member retained by both the rotatable ring and the collar so that the lancet depth adjustment member is rotatable relative to the housing to provide for a plurality of stop surfaces for the collar as the collar moves along the longitudinal axis to the distal end.

Abstract
Described and illustrated herein is an exemplary lancing device. The exemplary lancing device comprises: a first housing having spaced apart proximal and distal ends disposed along a longitudinal axis; a chassis disposed in the first housing in a fixed relationship with the first housing; a movable member disposed in the chassis and configured for movement along the longitudinal axis and in the first housing; a lancet coupled to the movable member; and a lancet depth adjustment member retained by both the first and chassis so that the lancet depth adjustment member is rotatable relative to both housings to provide for a plurality of stop surfaces to the movable member. Other embodiments and methods are also described.

11. A lancing device comprising:
-
a first housing having spaced apart proximal and distal ends disposed along a longitudinal axis; a second housing disposed in the first housing in a fixed relationship with the first housing; a movable member disposed in the second housing and configured for movement along the longitudinal axis; a bias member located in the second housing to bias the moveable member in a direction towards the distal end; a lancet coupled to the movable member so that the lancet moves as a unit with the movable member along the longitudinal axis; a depth adjustment member having a plurality of stop surfaces disposed radially about the longitudinal axis; and a rotatable lock ring engaging an inner surface of the first housing and an inner surface of the depth adjustment member to retain the depth adjustment member to the first housing in one radial position of the rotatable lock ring and to allow release of the depth adjustment member in another radial position of the rotatable lock ring relative to the longitudinal axis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A lancing device comprising:
-
a housing having spaced apart proximal and distal ends disposed along a longitudinal axis, the housing being devoid of any actuator or button on its outer surface; a movable member disposed in the housing and configured for movement along the longitudinal axis; a lancet coupled to the moveable member; and a cap enclosing the lancet, the cap having a plurality of fingers that extend along the longitudinal axis to engage the moveable member and move the moveable member towards the proximal end against a bias force such that at a predetermined position along the longitudinal axis, the plurality of fingers disengage from the moveable member to allow the moveable member to move in an opposite direction toward the distal end, thereby allowing the lancet to extend through the cap.

22. A method of operating a lancing device having a housing with spaced apart distal and proximal ends disposed on a longitudinal axis, a moveable member having at least one arm extending along the longitudinal axis, the moveable member disposed for movement along the longitudinal axis in the housing, a collar being in contact with the moveable member, the collar configured to retain a lancet, and a cap having a plurality of fingers extending along the longitudinal axis into the housing, the method comprising:
-
pushing the at least one arm of the moveable member towards the proximal end against a bias member with the cap via at least one of the plurality of fingers of the cap with the lancet being disposed entirely within the cap; and disengaging the at least one arm of the moveable member from the at least one of the plurality of fingers of the cap to allow the bias member to push the movable member with the lancet toward the distal end through an aperture defined by a wall of the cap to extend from the cap.

23. A method of operating a lancing device having a housing with spaced apart distal and proximal ends disposed on a longitudinal axis, a moveable member having at least one arm extending along the longitudinal axis, the moveable member disposed for movement along the longitudinal axis in the housing, a lancet member retained by the moveable member, and a cap having at least one extension portion extending along the longitudinal axis into the housing, the method comprising:
-
translating, with translation of the cap, the moveable member in a first direction along the longitudinal axis towards one of the ends of the housing; and accelerating the moveable member in a second direction opposite the first direction to extend a lancet of the lancet member beyond a periphery of the cap.
